Restore Your GM’s Electrical Functions with a Plug-and-Play Solution
If you’re dealing with bizarre electrical issues in your 2014-2016 Buick LaCrosse or other compatible GM vehicle—like power windows with a mind of their own, flickering dash lights, or a security system that won’t cooperate—a failing Body Control Module (BCM) is often the culprit. As the central hub for your car’s body electronics, its failure can cause widespread, frustrating problems. This isn’t just a replacement part; it’s a complete, hassle-free solution. We provide a professionally programmed 2014-2016 LaCrosse BCM that is ready for installation right out of the box, eliminating the need for expensive dealership programming.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Chevy Malibu with a classic case of electrical chaos. The radio would cut out, the interior lights would pulse randomly, and the key fob worked intermittently. They had already replaced the battery and checked the main fuses. After hooking up my scanner, I saw multiple communication loss codes (U-codes) pointing to the BCM. Instead of sending them to the dealer for a new module and a hefty programming bill, we used our cloning service. We transferred all the original data to our replacement module. The customer had their car back the next day with all issues resolved—no key relearn, no extra fees. This is the exact service we offer you.
How Our Simple Cloning Service Works
To ensure a seamless repair, this BCM is supplied through our mail-in programming service. This process transfers your vehicle’s unique identity—like the VIN, key information, and specific options—from your original BCM to this replacement unit. The result is a true plug-and-play module that restores function without conflicts. After your purchase, we will contact you with clear, step-by-step instructions for shipping your original module to our facility. Once we receive it, our technicians will perform the data transfer and ship your new, ready-to-install BCM back to you promptly.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ The anti-theft or security system light is on, or the vehicle won’t start.

A Straightforward Guide to Installation
- ✔ Step 1: After purchase, follow our instructions to safely remove your original BCM and ship it to us. The BCM is typically located in the driver’s side (LH) kick panel on the LaCrosse.
- ✔ Step 2: Once we receive your module, we will clone the data to the replacement unit and ship it back to you, providing tracking information.
- ✔ Step 3: Disconnect the negative battery terminal to ensure safety.
- ✔ Step 4: Carefully unplug the electrical connectors from your old BCM and remove it from its mounting bracket.
- ✔ Step 5: Install the newly programmed BCM, ensuring it is securely mounted and all connectors are firmly seated.
- ✔ Step 6: Reconnect the negative battery terminal and test all functions (lights, locks, windows, etc.).
Important Post-Installation Information
In some cases, additional synchronization procedures may be required after installation. These are typically simple steps for a qualified technician with a professional diagnostic tool.
- Airbag System Sync: If the airbag warning light is illuminated after installing the BCM, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is only necessary if the light appears.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary on certain models.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a professional technician for specific guidance.
